Android/iOS: Twitter released an update to its mobile apps that brings photo filters to its image service alongside some basic photo editing abilities.

To edit a photo, just click the image icon, select the picture you want to use (or take a new one), and you'll get the edit photo page. Here you can apply one of eight filters, crop the image, or run an auto-enhancer that adjusts the balance. The Android version is available right now, and the iPhone version should be out shortly.
